Summary

Radially distorts the image by creating waves that twist the image around a specified center. This command is available in the Imaging Pro and above toolkits.

Syntax

C++/CLI

Python

public class ZigZagCommand : RasterCommand

public ref class ZigZagCommand : public RasterCommand

class ZigZagCommand(RasterCommand):

Remarks

As an example, if you use the following image:

And you were to call ZigZagCommand using the following settings:

Parameter	Value
Amplitude	47
Attenuation	92
Frequency	13
Phase	-162
CenterPoint	(192, 82)
FillColor	Black
Flags	Color \| RadialWave

The following figure results:

As another settings, if you use the same settings except you use the PondRippleWave flag, the following figure results:

If the image has a region, the effect will be applied on the region only.
This command supports 12-bit and 16-bit grayscale and 48-bit and 64-bit color images. Support for 12-bit and 16-bit grayscale and 48 and 64 bit color images is available only in the Document/Medical toolkits.

Example

Run the ZigZagCommand on an image and applies the ZigZag filter.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.SpecialEffects; 
 
 
public void ZigZagCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
 
   // Prepare the command 
   LeadPoint ptCenter = new LeadPoint(192, 82); 
   RasterColor fillColor = new RasterColor(0, 0, 0); 
   ZigZagCommand command = new ZigZagCommand(); 
 
   command.Amplitude = 47; 
   command.Attenuation = 92; 
   command.Frequency = 13; 
   command.Phase = -162; 
   command.CenterPoint = ptCenter; 
   command.FillColor = fillColor; 
   command.Flags = ZigZagCommandFlags.Color | ZigZagCommandFlags.RadialWave; 
   command.Run(image);
